Resteasy application always returning 404s


I started an application with only these two classes as a sanity test, but I only get 404s. I run a get request from Postman at localhost:8080/TestApi-1.0-SNAPSHOT/test, which should hypothetically return "Hello World" but I get a 404 response. I'm using JBoss/Wildfly 14.0.0-Final as the server for reference. Any help would be appreciated. I'll include the two classes, the console output when deploying the server from IntelliJ, and the POM.

<------------------- TestEntry.java ------------------------>
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/")
public class HealthyLivingApiEntry extends Application {
}

<------------------- TestResource.java ------------------------>
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;

public class HelloResource {

    @Path("/test")
    @GET
    public Response hello(){
        System.out.println("Running test service here");
        return Response.ok("Hello World").build();
    }

}

Solution

  • Changing TestResource.java to look like below helped. Looks like for some reason a class isn't recognized as a resource with the @Path annotation.

    <------------------- TestResource.java ------------------------>
    import javax.ws.rs.GET;
    import javax.ws.rs.Path;
    import javax.ws.rs.core.Response;
    
    @Path("/")
    public class HelloResource {
    
        @Path("/test")
        @GET
        public Response hello(){
            System.out.println("Running test service here");
            return Response.ok("Hello World").build();
        }
    
    }
